"IMPROVEMENT IN CUT-OFYFS FOR PIPES.

The Soheulc-referred to in these Letters Patent and making part of the sanne.

To all whom it may concern:

g 'Be it known that I, JAMES H. PERKINS, of Omaha, in the county of Douglas, and State of Nebraska, have invented a new and useful Improvement in Cut- `Ott for Pipes; and I do hereby declare that the following is a full, clear, and exact description thereof, which'will enable those skilled in the art to make and use ille saine, reference heilig had to the, accompanying drawing, forming part 0f this specification.

My iuveption has for its object. improvement in that class of water out-offs, which consist, in general terms, of a pipeprovided with a hinged conductor, and relates to the peculiar construction of parts, as hereinafter set forth.

Figure 1 represents aside elevation of myitnproved cut-ott' device, and

Figure' 2 represents a sectional elevation of the same.

' A and Bare two sections of pipe, joined together by sliding the reduced ends of the latter into the end ofthe former, which is shaped obliqncly at Athe end, as represented hy the'line C.

The end of the sectit n B is also oblique, but less s0 than the other, andthe oblique lines are arranged opposite to those ofthe section A.

This arrangement makes a'n opening between the. ends ofthe. two sections at the short'sides, the one not beinginserted in the other too far. At this opening 1 arrange a spontor chute, 1), consisting of a shorteurred tioat with oval ends, by hinging it to the part A by a link, E, capable of folding into the pipes through the opening.

lhc upper end of this spout is provided with a hook, F, and each section, A B, has a staple, G, for thesaid hook.

This spout has a curvature about equal to that o f the partsA VB, and .the lower end projects into the lower parts, and is curved on its end so that when turned down in the position represented in tig. 2, and pressed up against the wall ot'the pipil A at B, it will titsnngly the curvature thereof, and elose the direct downward passage. '.lhe .other end of this spout laps the upper set-tion outwardly, when adjusted to the position shown in tig. 2. f

The hook F, when engaged with the upper shaft Gr, will hold -thespout in the position to permit the water to pass directly down, and when engaged with the vlower staple, it holds the spout in the position vto direct the water from the said downward passage.

This apparatus nity be tnade in the complete form.

represented inthe drawings, ready for attachment to any pipe, by separating two sections thereof.

Heretofore, water cut-offs, constructed and operat im on the suine general planas mine, have consisted ot single sections of pipe, cut ont on one rsidefftnd provided with a gate'hinged thereto in such a manner as to foldinto the ope-ning. When the gate or chut.,

in these devices .is closed, the water cannot be prevented t'roiu escaping more or less between the edges vof the chute and pipe-section,`

When the chute is open, a lip or-flange must be providsdon the interior ot' the pipe, to prevent water.

from passing downward between the inner-end of the chute and the inner wall or side ofthe pipe, since the chtite is hinged in such a in anner that said' end cannot. be; ninde to nipinge on the pipe and still have the inclined position `requisite for delivering the water, as is the ease in niy invention.

However, to obviate all contingency of leakage, should the two sections of pipe be placed at a slight angle to` each other, l have curved the end of one ot'- `said sections, as previously indicated.

'lhis'diit't-rence renders niy device greatly superior for its intended use. Having thus described myinv'ention,

What l elaiin as new, and desire to secure by Letters latent, is g .'lhe sections A andv l, obliquely shaped at their contiguous ends, and so arranged, one within the other, as to tt r.n an openingtbrthechnte l), which is hinged to the part A by the link E, all constructed and ar- ,1'

ranged as specitied, whereby said chute will, when open, inxpinge at its inneijend on the inner surface ot? the pipe or curved end a of pipe B, and lap over .the pipe l when closed, asherein shown and described,

for the purpose indicated. v
